GAS-STOVE TOP.

Application filed July 24, 1915.

To all whom it may con cern Be it known that I, 'WILLIAM. W. SMITH, a citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Gas-Stove Tops; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to stove tops, and more especially to the elevating supports intended for use on the tops of stoves which employ fluid or gaseous fuel, and the same embodies improvements over the construction described in my U. S. Patent No. 1,148,412, dated July 27, 1915.

The features of improvement are elaborated in the following specification, shown in the drawings, and specifically covered in the appended claims.

In said drawings: Figure l is a plan view showing the application of this attachment to the top of an ordinary gas stove. Fig. 2 is inverted perspective view of a special form of main section with one side section in place, and Fig. 3 is a sectional view of this main section and two side sections, showing its application to the top of a stove. Fig. l is a perspective view of another special form of main section, showing its application to a certain make of gas stove. Fig. 5 is a perspective detail of one end of one of the side sections showing a right-angular tongue, and Fig. 6 a perspective detail of a filler section broken away at the center, this view showing a T-shaped angular tongue. Fig. '7 is a perspective detail of a special form of side section, Fig. 8 shows its application to one side of a main section, and Fig. 9 is a sectional detail on the line 9-9 of Fig. 8.

Most gas stoves now in use have a grated top G surrounded by a solid frame F, and at certain points beneath the grate, usually between the removable sections or spiders therein, are located burners B which are fed with fluid fuel through a main pipe I valves V and mixers. M. The prevailing custom is to employ burners with the neces- Specification of Letters Patent.

sary adjuncts in rows of two or more, commonly of two, one near the front of the stove and the other farther back. Forward and backward of the stove the spacing of the burners in the many types of gas stoves is nearly the same; but laterally the spacing difiers with different manufacturers. Again, some makes of gas stoves have rather wide frames F, some add shelves or ovens at the.

sides, and some widen the frames at the rear where they are perhaps provided with upstanding fines U to carry off the products of combustion. Therefore provision is made in my former patent for widening this attachment to correspond with the width of the top of the stove, and for reducing the length of this attachment to correspond with the depth of the top of the stove. But I find in certain makes of gas stoves that the two rows of burners are so close together that the standard main sections useful on most gas stoves cannot be employed, and a special form of main section is necessary having four lid openings and otherwise adapted in detail to this make of gas stoves, and this feature of my present invention is shown in Figs. 2 and 3. I also find other forms of stoves on the market, best shown in Fig. 4:, in which the gas stove S is formed at the side of a coal stove C, but usually there are three burners disposed in a single row and there are large air inlets A at the front of the structure in addition to the space around the mixers M as shown. This type of gas stove requires another special section whose use is illustrated in Fig. 4. In all cases, however, I find it desirable to close the sides and front ends of the attachment against the escape of heat or the entrance of cold air, and to leave the rear end of the attachment open for the escape of the products of combustion. This is brought about in the present case by special forms of side sections best illustrated in Figs. 5 and 7 I find by experience that it is not always necessary to fasten this attachment to the top of the stove, and that when I do so it is not desirable to bore holes in the top as in my patent; and in the present case I bolt the attachment to the grate as indicated at the leftof Fig.

1. Whether the attachment is or is not fas tened to the stove, I find it desirable to connect thevariou's sections by 'means ,which will prevent their disconnection or .atheir relative movement so long as their top plates lie in a single plane;vand Lshaped tongues for this purpose are shown in Fig." 5, and

T-shaped tongues in Fig. 6.

Referring by numerals to the drawings,

the attachment as applied to the ordinary form of gas stove ismade up of two .maln' sections 1, 1, an interposed filler section 21 and two-side'sections 31, 31. The" main and filler sections have transverse slats 5 across their rear ends," withbreak-lines so that they may 'be'removed to'adapt the length ofthese sections to the depth of th'e top 'ofthe stove and to cause the attachmentfto surround a flue. U when iteXists. The main sections in this, as in all forms o f'fthe present inven-' tion, have'lid openingsS wholly or partly surrounded by depending flanges and closed by the pots or by" removable lids a. In main sections of standard make, the two lid opento fill out this attachment at its edges and adapt it to the Width of the frame F. The filler section is supported at its front end by 'a flange 24- and at itsrear end by legs 29. Eachi'nain section is supported atits corners by legs 11 which rest directly on'the frame F, and along one or both sides it has depending flanges 10 cut out at l2'between the legs so as to pass over the grate G as seen in Fig. 3, and notched at standard intervals as at 13. With these notches are en-- gaged tongues projecting from the contiguous edges of the supplemental sections for holding allsections connected as long as they remain in a single plane, and finally it is possible tobolt the attachment to the top ofa gas stove. All of the features thus far described are set forth in my patent, and no claim is made thereto herein.

The front fianges'24 and 34 of the supplemental sections are as wideas the length of thelegs 1 1,as' a lso-is the side flange 30 of each side'section 31. The front-flange 8' of each main section may also 'bemade of'the V samewidth, although in Fig. 2 I have-shown it filed offorcut out a little atf9 along its lower edge to pass over irregularities in the.

frame F or screw.headsrising'above it, and to permit the escape of thezmoisture' of condensation; Thiswiewaalsoshows how the side fiange 30 may be filed .off or cutl out a little along. itslower edge at 39, but we-may say that the flanges 8 and 30 come down practicallyinto contact with the-f frame F, as do the flanges and 24' and the" legs 11.

; The numeral. 23 jdesignates'a which may be east beneath the tiller section for strengthening purposes, but it isv not of;

width enough to impede the flow of heat I beneath this section. The special: main sec? tion 'shown inFig. 2 has a rib 1 17 running 7. its entire length between its tworows of openings 3, but the lower edgeof this rib is if cut out as at 12 like: the side flanges 10 therefore itidoesnot seriously impede the.

flow of heat. The rear end of .5 this ribiby preferencehas aspecial leg ll to support thecenter of the section at its rear end. 2

The standard main sectiens' I I "may" have, Fl. notches 13' in both their side flanges 10, as? are shown in both side flanges of the: special main section 1 of Fig. 2;" but :I, find thatit- I tions along both edges of the main section, and where such side sections-are notto be and in Fig. 4:110 side sectionis shownat the rear of the main section 1", and the flange" 30 along the left side will come'down I practically into contact with the frame F..

The result of this improvement is that, with or without the use of side sectien's, the front end and both sides of the attachment are 'is not'alwaysnecessar'y to apply' side sec- '90": used the main sections may have full width flanges such as those illustrated at 30 inFig,

This may apply to a standard main sec tion-or to a special form of main section, i

closed to the escape "of heat or the inlet of cold air. Air to supply productsof com bustion mustfind its entrance through the and theproducts of combustion can escape fix I out the rear end of the attachment or beopenings provided for it in the gas stove,

tween its slats 5.

In applying this attachment to the tops"'-' 3 I of-gas stoves of a variety of makes, it some-- 7 times occurs that even the narrowest side 7 section as shown in Fig. 5 and' as' shown 7 30 would come out almost to the corner'of the frame F and a neat fit could not be made. 1 I have therefore devised aspecial form ofside section best seen in Fig' 7.

This can be made of sheet metal out into the shape' of a fiat's'trip '36 having'integral tongues 35 progectingfrom one =-edge at standard intervals, these:

tongues being applied in Fig. 4- is so wide that-its flange 1 3 angularand of-L-shape or T-shape as here inafter described, and bei the side flangelO of a main section, it is laid against 'suc h flangeiwith itsshanks" opposite thenotches 13. and then'moved 1110- i ward so that the shanks enter Ethe notches e ng bent as cbest' -j- SSE-11111 Fig. 7. -=-In apply ng this section to I and the heads of the tongues slip in behind the flange as shown in Figs. 8 and 9. The strip may be of a width a little less than the length of the legs 11, but in any event its lower edge rests on the frame F and its body covers the space beneath the cut-out 12 while of course it closes the notches 13. The result is that this special side section serves to prevent the escape of heat or the admission of cold air, and therefore possesses the advantages already described.

Along the edges of the supplemental sections are tongues for engaging the notches 13, these tongues being on both edges of the filler section as seen in Fig. 6 and on the inner edge of the side section as seen in Fig. I prefer to make said tongues angular, and have employed Fig. 6 to show them as of T-shape as at 25, while 1 have employed Fig. 5 to show them as of L-shape as at Obviously any other angular configuration could be given them, and the shape adopted could be used on all the supplemental sections. In the application of this attachment to a stove top, two standard main sections are selected if the stove is of usual make or a special form of main section if the make of the stove necessitates it. \Vith two main sections 1, a filler section 21 will be interposed as shown in Fig. 1, and this section must be of such width as to space the openings 3 to correspond with the rows of burners. One or more side sections 31 are then applied to fill out the width of the attachment and cause its periphery to parallel the edge of the frame F so as to produce a neat job, and here again side sections of proper width must be selected, even if it is necessary to use an extremely thin section as shown in Fig. 7. With special makes of stoves, a special form of main section will be employed, and in this case there is no filler section and there may be one or two side sections as may be required. In any event, however, I close the front and both sides of the attachment with supplemental sections which rest upon the frame F, unless the side flange or flanges of the main sections are sufliciently wide to do so.

One important feature of the present invention is that when the parts of this attachment are assembled, they cannot be moved relatively as long as they remain in a plane. This results from the use of angular tongues such as those described, whose shanks engage with the notches 13 in the main section or sections and whose tips are bent aside at right angles behind the flanges 10. If thought desirable, a bolt 18 may be passed down between the slats 5 and through the grate G, where it will receive a washer and a nut, and in this way one or both main sections will be connected with the grate and therefore with the stove, while the supplemental sections are connected with the main sections by the means just referred to. I prefer to make the side section of a length coincident with the depth of the shallowest gas stove on the market, and its rear end is closed by a flange 34: as shown in Fig. 1. The other standard sections are longer, and the slats 5 may be broken off to adapt the attachment to the depth of any stove. The special forms of main sections will not need this feature at their rear ends, as they are made especially for certain types of stoves. The manner of fitting and applying this attachment to a stove top and of using it when placed thereon need not be elaborated.
